| STP 1921 is a high quality, neutral, elastic single component adhesive/sealant based on Silane-terminated Polymer, which cures by reaction with moisture to an elastic product. The skin formation and curing time are dependent on humidity and temperature, and the curing time also depends on joint depth. By increasing the temperature and moisture these time can be reduced; low temperature as well as low moisture retard the process. STP 1921 is a good compromise between an adhesive and a sealant based on Silane-terminated Polymer. STP 1921 is suitable for elastic seal which also high strength is required. STP 1921 is odourless and free of solvents, isocyanates, silicones and PVC. It demonstrates good adhesion without primer to many substrates and is compatible with suitable paint systems. The sealant also demonstrates good UV resistance and therefore can be used for interior and exterior applications. Features and Benefits: - Odourless
- Non-corrosive
- Primerless adhesion on many substrates
- Colour stable and UV resistant
- Ecological advantages – free of isocyanates, solvents, PVC
Typical Applications:- Elastic bonding of metals and plastics.
- Elastic, interior and/or exterior seam and joint sealing.
In the following areas: vehicle body, caravan, railway carriage, container, general metal and apparatus construction; the electrical, plastics, air-conditioning and ventilation industries.Information provided by H.B. Fuller Company |
